I've calculated how much the car depreciated every year which is about $3,757
In three years, that is 11,271.
$34,800 - $11,271= $23,528
The automobile cost $23,528 at the end of the third year.
If I’m not wrong the answer is -4 sorry if I’m wrong because I just started learning this
Answer:
x = -6
Step-by-step explanation:
x - 12 = -18
Add 12 to each side
x-12+12 = -18+12
x = -6
Answer:F(x)=-x2-3
Step-by-step explanation:We are given a function:
The graph of is also shown in the given question figure.
It is a parabola with vertex at (0,0).
Sign of is positive, that is why the parabola opens up.
General equation of parabola is given as:
Here, in G(x), a = 1
Vertex (h,k) is (0,0).
As seen from the question figure,
The graph of F(x) opens down that is why it will have:
Sign of as negative. i.e.
And vertex is at (0,-3)
Putting the values of a and vertex coordinates,
Hence, the equation of parabola will become:
The discriminante :
b^2-4ac
1^2 - 4 * -2 * -28 = 1 - 224 = -223
When the discriminant (b^2-4ac) is less than 0, the equation had no real solutions.
-223<0, so, 2x^2+x-28 = 0 has no real solutions.
Hope that helps :)
